Got it. Next, I'll add the regulator and backlight dt-binding into the
series patch.
And add the description into mfd core dt-binding like as below.

This patch depends on
    "backlight: rt4831: Adds DT binding document for Richtek RT4831
backlight module".
    "regulator: rt4831: Adds DT binding document for Richtek RT4831 DSV module".
